Then the old woman threw the robe about him and he was seen no more, but there was a wind as if the thunderbird flew towards the setting sun. His mother fell on her face as one dead, but the people heard a voice high in the air, clear and loud like the voices of the cranes when they fly towards the region of the pines, and this is what it said, "A stone shall free the Four Brothers."

When the Stone Boy went from the people he stepped from hill to hill more swiftly than the stars (meteors) fall at night. From each hill he looked carefully into the valley so that he saw all there was in every valley, but he saw nothing of the Four Brothers until he came to the high hills far towards the setting sun.
